20.3.1.Connection Object

The Connection object has the following capabilities:
 
Creates SQL statements
Executes SQL queries, inserts, updates, and deletes
Handles commits and rollbacks
Provides metadata regarding the database connection
 
By default, a Connection object is in autocommit mode, which means it automatically commits changes after executing each statement.

Connection對象具有以下功能：
 
創建SQL語句
執行SQL查詢，插入，更新和刪除
提交和回滾
提供關於數據庫連接的元數據
 
默認情況下，Connection對象是在自動提交模式，這意味着它會自動提交執行每個語句後的變化。
